Maximum inside diameter

Front side

21.527 mm (0.8475 in.)

Rear side

35.251 mm (1.3878 in.)

If the inside diameter is greater than the maximum, replace the stator shaft assembly.

INSPECT CLEARANCE OF OIL PUMP ASSEMBLY

Push the driven gear to one side of the pump body.

Using a feeler gauge, measure the clearance between the front oil pump driven gear and front oil pump body sub-assembly.
Standard body clearance

0.10 to 0.17 mm (0.0040 to 0.0066 in.)
1. If the body clearance is not as specified, replace the front oil pump drive gear, front oil pump driven gear and pump body sub-assembly.

Using a feeler gauge, measure the clearance between the driven gear teeth and drive gear teeth.

Standard tip clearance

0.07 to 0.15 mm (0.0028 to 0.0059 in.)

If the tip clearance is not as specified, replace the drive gear, driven gear and pump body.

Using a steel straightedge and feeler gauge, measure the clearance between both gears and straightedge.

Standard side clearance

0.03 to 0.05 mm (0.0012 to 0.0019 in.)

If the side clearance is not as specified, replace the drive gear, driven gear and pump body.

HINT:

There are 7 different thicknesses for the drive and driven gears.
